BODMAS explained

Build equations that hit the target by applying the order of operations correctly. Also known as BIDMAS, PEMDAS, order of operations.

The rules

Brackets first, then Orders (powers and roots), then Division and Multiplication from left to right, then Addition and Subtraction from left to right.
In the game, fill the equation boxes with numbers, brackets, fractions and powers so the expression equals the target.
Each round has 15 questions, with step-by-step feedback showing how your expression is worked out.

Choose a mode and press Start Game.
Fill the equation boxes using the keypad — numbers, brackets, powers (x², x³) and fractions.
Submit to check; the animated breakdown shows how the expression is worked out.
After 15 questions, the summary shows your score and what to focus on.

Target 20 using 2, 3 and 4: 2 × (3 + 4) = 14 is too small; (2 + 3) × 4 = 20 works because the bracket is worked out first.

Without the brackets, 2 + 3 × 4 = 2 + 12 = 14 — the same numbers, a different answer.

Multiplication binds tighter. 3 + 4 × 2 is 3 + 8 = 11, not 14. Use brackets — (3 + 4) × 2 — when you mean 14.
Left to right for equals. Division and multiplication have equal priority: 12 ÷ 3 × 2 = 4 × 2 = 8.
Powers before multiplication. 2 × 3² = 2 × 9 = 18, not 36.
Check with the breakdown. After each answer, read the step-by-step breakdown — it shows exactly which operation happened first.

Working strictly left to right: 6 + 6 ÷ 3 is 8, not 4.
Thinking M comes before D because it comes first in the word. They have equal priority; go left to right.

Mnemonics like BODMAS (UK, Australia), BIDMAS and PEMDAS (US) all describe the same convention, used in mathematics for well over a century.

Is BODMAS the same as PEMDAS?

Yes. Parentheses = Brackets, Exponents = Orders; multiplication/division and addition/subtraction are each done left to right.

What year level is this for?

Order of operations is taught from about Year 5–6 and revised through Year 8; the game's modes cover simple to advanced expressions.

Does the game show working?

Yes — an animated step-by-step breakdown after each question.
